Definitions

  • the charge of material M is transferred from the melting unit 82 to the shot tube 64 in a known manner, such as pouring the charge of material M into a pour hole 63 in the shot tube 64, for example.
  • a sufficient amount of molten metal is poured into shot tube 64 to fill the die cavity 60.
  • the shot tube plunger 68 is actuated to inject the charge of material M under pressure from the shot tube 64 into the die cavity 60 to cast a component 55.
  • the die casting system 50 could be configured to cast multiple components in a single shot.
  • composite is used to die cast the component 55.
  • composite is defined as a refractory metal intermetallic composite (or, RMIC).
  • RMIC's contain a member or members of the family of refractory elements. These elements include tungsten, rhenium, tantalum, molybdenum, and niobium. These elements are combined with an intermetallic element such as silicon.
